WILLIAM SCHEIDEL, OF CHICAGO, ILLINOIS.

SPECIFICATION forming part of Letters Patent No. 766,468, dated August2, 1904.

Application filed December 31, 1903. Serial No. 187,277. (No model.)

To (ti/Z 1072 0111 it may concern.-

Be it known that I, IVILLIAM SCHEIDEL, a citi- Zen of the United Statesof America, and a resident of Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements inRectiiying and Interrupting Alternating Currents, of which the followingis a specification.

The present invention relates to the appliances and circuits used inoperating inductoriums and like apparatus, in the operation of which ahigh-frequency current is employed, and has for its object to provide asimple and efficient structural arrangement and combination of partswhereby alternating or other like variable electric currents areeffectively utilized in the operation of inductoriums and the like andwhich is adapted to eliminate to a very material extent the usual rapidgeneration of heat and increase in temperature in the ordinaryform ofelectrolytic interrupter when working with alternating currents, and insuch elimination of heat attain a constant and effective high-frequencyinterruption of the current supplied to an inductorium or the likeduring long-continued use of the apparatus, all as will hereinafter morefully appear, and be more particularlypointed out in the claim.

In the accompanying drawings, illustrative of the present invention,Figure l is a diagrammatic view illustrating the general arrangement ofthe present apparatus. Fig. 2 is a vertical section of an electrolyticinterrupter embodying the present improvement.

The present improvement involves the rectification of alternating andlike variable electric currents during the passage of the same through ahigh-frequency electrolytic interrupter, so that the dual operation ofinterruption and rectification will occur in a substantiallysimultaneous manner in the single cell of the present apparatus, andwith which the passage of one phase of an alternating or like variablecurrent through such cell is prevented, while free passage is affordedto the other and companion phase of such alternating or variable currentand a simultaneous high-frequency interruption of such last-mentionedphase efi ected prior to its passage to the primary winding of theinductorium or other like apparatus.

To such end the present invention consists in the formation of thecathode element or electrode of the electrolytic interrupter fromaluminium or other equivalent substance which when acting as a cathodeofl ers but little resistance to the passage of the electric current,but which when acting as an anode prevents the passage of such current.The other element or electrode of the apparatus is formed of platinum,carbon, or the like, while the electrolytic fluid will be phosphate ofsoda, or

scribed, and which constitutes the cathode element or electrode of thepresent apparatus and to the end is provided with a bindingpostconnection 7 for one of the line-wires of the alternating electriccircuit of the system.

8 is the anode element or electrode formed of platinum wire or likesubstance and secured in the lower end of a hold er-rod 9, which issuitably connected with the other line-wire of the circuit of thepresent system.

10 is a tube of insulating material surrounding the anode 8 and having asmall orifice at its lower end through which the said anode 8 projectsinto the electrolytic solution in the cell 6, as shown and as usual inthe present type of interrupters.

The difierent adjustments of the parts shown in Fig. 2 are the same asin my prior patent, No. 716,583, dated December 23, 1902.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

In a combined high-frequency interrupter passing through the apparatus,substantially I0 and rectifier of the character herein described, as setforth. the combination of a containing-cell formed of Signed at Chicago,Illinois, this 29th day of aluminium or the like and constituting theDecember, 1903.
